Specification of Letters Patent.

Patented Jan. 20, 1920.

Application led March 2, 1918. Serial No. 219,961.

To all 'whom it may concern.'

.Be it known that I, XVM/rim R. LANUM, a citizen of the United States, residing at Savannah, in the county of Chatham and State of Georgia, have invented certain new and useful Improvements in Heaters, of which the following is a specification.

This invention relates to new and useful improvements in heaters, and the primary object of the invention is to provide a heater of this character embodying a novel arrangement of parts, whereby a long flame receiving chamber is formed that enables a maximum amount of heat to be obtained at a minimum expenditure of fuel.

Another object of the invention is to pro'- vide a heater of this character which is provided with an inverted substantially U- shaped body portion, that has the fire box in one end thereof whereby a long flame chamber is provided that creates a great amount of heat compared with the amount of fuel used, said chamber havingl the smoke outlet disposed at the opposite end thereof which is outwardly turned, and is raised slightly above the base upon which the heater is mounted.

A further object of the invention is to provide a device of this character which is easily and simply constructed, inexpensive to manufacture, and one which will be very efficient in operation.

With these and numerous other objects in view, my invention consists of the novel features of construction, combination and arrangement of parts which will be herein referred to and more articularly pointed out in the specification and claim.

In the accompanying drawings:

Figure 1 is a vertical longitudinal section through the heater, v

Fig. 2 is a vertical section on the line 2-2 of Fig. 1, and

Fig. 3 is a side elevation of a slightly modied form.

In describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views.

The numeral 1 designates the base upon which my heater is mounted which is substantially flat, the same being supported by depending legs 2 disposed adjacent the opposite ends thereof. Upon the base 1 is mounted a heater, which is formed of an inverted substantially U-shaped body portion 3, and

includes the relatively long. and short sides or vertical members 4l and 5, the member 4 resting upon the base 1 adjacent one end thereof, while the other side 5 terminates short of the base, and is supported thereon by depending supporting legs 6 that extend from an outwardly extending portion 7 at the outer end thereof. The outwardly extending portion T terminates in a projection S communicating with said end through an outlet, whereby smoke is permitted to escape from the body. The smoke pipe is connected with the projecting portion 8 to carry the smoke to the outside or to any place from which it may be discharged.

The sides et of the body receives a fire box therein, which comprises a grate 9 of the usual type, raised slightly above the base 1 and the front is open and provided with a door as shown at 10 so that ashes may be removed therefrom. The front of the heater is also provided with a fuel inlet provided with a closure 11, whereby fuel may be fed to the heater. The portion of the body adjacent the lire box is surrounded by an inner lining 12 that prevents the walls of the heater from being burnt through.

In the modified form of heater, the latter is provided with side closures 13, as clearly shown in Fig. 3 of the drawings, that are preferably provided with openings 13a and are hingedly supported. The rear portion of the body is provided with a closure plate 14; extending downwardly therefrom to the base. This forms a heating space between the side walls t and wall 5 of the heater which may be used as an oven when so desired.

The operation of this type of heater is very easily understood. The fuel is fed thereto to the fire box, through the opening 11, and when the same is ignited the flame will be carried up through the body, said body owing to its peculiar shape forming a long but compact flame conducting and heat radiatlng chamber that produces the greatest amount of heat at a minimum expenditure of fuel. The smoke is carried off through the smoke outlet at the outer end of the heater through the smoke pipe to the place to which it is discharged. This type of heater may be formed of various sizes, but it is preferably adapted to be of compara tively small size, so that it is portable and may be easily moved from place to place. The side closures when used adapt the device to be used for a cooking oven or warming oven, as food placed between the sides of the chamber, and underneath the extending portion 7 on the base l, will be thoroughly heated and cooked, as is obvious.

F or the foregoing description, taken in connection with the accompanying drawings, lit is thought that a clear and comprehensive understanding of the construction, operation, and advantages of my invention may be had, and while I have shown anddescribed the device as embodying/a specific structure, I desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope of the invention as claimed.

its lower end, a grate supported in the other vertical member of the body, a hinged closure plate depending from the horizontally extended portion of the body, and opposed side plates hinged to the bodyy and adapted to close the space between the vertically disposed members thereof.

In testimony whereof, I aflix my signa- WALTER R, LANUM,

ture hereto.
